U. I am found in the Earth's crust and I blow stuff up. I also like to create power for other people in powerplants. I have a softer side I can also be in glass ceramics.
Be. I am reactive. Don't touch me or I will blow espically if you are water.
H. I am all alone because I have no family. :(Please stay away from me I'm in rocket fuel, so I could go off at any second.
He. I am used in all different types of balloons. I like to mess with peoples voices. Purpose: To find out which chemicals form a solution with water.=IV: Type of chemical.
DV: If it forms a solution with water.
Constants: amount of each chemical, amount of water, type fo water, temperature of water, amount/ type of mixing.
Measure out 20ml of water from the sink, add to test tube.
Place a tip of the scope of a chemical in a test tube.
Place black stopper on top & mix.
Record your obserations.
Repete these steps 5 times(one time per chemical).

1/31/08 Tips Searching for things on the Internet
Make sure that the info that you are getting is correct.
Use well-know web-sites.
Read everything that you find.
Try different websites like; How Stuff Works.
Use different search engines like: Google, Ask.com, Yahoo, Dogpile.com.
Use resources sugested by your teacher.

Fossil Fuels: Fossil Fuels are nonrenewable energy resources that form in the Earth's crust over millions of years from the buried remains of once-living organisms.
Energy Resource: A natural resource that can be converted by humans into other forms of energy.
The differences between Nonrenewable Energy & Renewable Energy is that the Nonrenewable Energy can not be replaced whereas Renewable Energy can.

Energy is the abilty to do work.
The two main types of energy are Kinetic & Potential Energy.
Forms of energy: Thermal, Chemical, Electrical, Sound, Light, Nuclear, Gravitational Potential Energy
Kenetic Energy- energy of motion (depends on mass speed).
Potential Energy energy of shape or position, stored energy (depends on hight anf weight).

Questions 3, 4, and 5 page 272
3. Conductors conducts energy, Insolators keeps it in or out.
4. Conduction distriputes the energy through direct touch, Convection distributes energy throughout the liquid or gas.
5. States of matter is the state in which matter exsist, Change of state is the change of the State of matter.
Adam: Solutions are transparent liquids. Things are disolved in solutions. **mms1-ad**

Dalton:
All substances are made of atoms. Atoms are small particles that cannot be created, divided, or destroyed.
Atoms of the same element are exactly alike, and atoms of different elements are different.
Atoms join with other atoms to make new substances.
3-3-08
copper sulfate, sucrose, and sodium chloride formed solutions.
zinc oxide was cloudy sulfur was clumpy.
MAKE SURE YOU WRITE A WEB! don't skip anything Tom:
NOTES:
Seperating mixtures:
1.The particles in a suspension are to big to go to the filter so filteration will seperate a suspension.
2.The particles in a solution are very small and pass right through the filter paper so filteration will not seperate.
3.Evaporation can be used to seperate a solution.
4.Decanting a suspension that has settled will seperate the parts. Collin:
Helium Notes
3-26-08 Democritus:
Thought that the smallest particles in an object was an atom.
Nothing can be cut in half forever, so there must be a smallest particle. He named them "ATOMS" which means that it is "uncuttable".
Lived around 440 B.C.
He was not a sciencetist but he was a Greek philosopher.
Dalton:
Atoms joined with other Atoms to form other substances.
Atoms of the same element are exactly alike and Atoms of different particles are different.
Atoms are small particles that cannot be distroyed.
Thomson:
There are smaller particles inside an Atom called Electrons
Discovered that Electrons are negatively charaged.

Soluble- able to disoulve. Insoluble- not able top disoulve.
Solvent- the substance in which a solute is dissolved to form a solution Solute- the substance that is dissolved to form a solution Solution- a mixture that appears to be a single substance but is composed of particles
of two or more substances that are distributed evenly amongst each other. Dissolve- When the solute particles particles break apart and mix in with the solvent particles. Links:
